Use of a bypass capacitor results in slower current change. 3 Measured with internal bypass capacitor (0.1 µF) between VCC and GND. Additional bypass capacitance results in slower current change. 4 Guaranteed by characterization and design. 5 Power-Up State as defined is true only with a VCC slew rate of 25 mV/µs or greater. 6 For t > ton and BRP < B < BOP, Power-Up State is not defined.
